I’m no camper pro, but I believe my dad’s Dutchman camper that I borrow on occasion is a 24’, also 2 axle with no slide outs. It’s not bad, like most campers it’s built a little on the flimsy side to keep weight down. I think that one is a little over 5,000 fully loaded. That’s about the max size of camper I would personally want to haul with any half ton pickup, no matter what weight it’s rated to tow. Use a good weight distributing hitch.
The weight isn’t the issue as much as stability and wind when hauling a relatively light, high profile trailer. I’ve hauled horse trailers, dump trailers, heavy flatbeds, ATVs, sleds, gooseneck, bumper pull, etc. with a bunch of different 1/2 ton and 3/4 ton pickups for work and for fun, and campers tend to be a pain in the ass to tow comparatively.
Also, don’t trust the tires that come with any camper and keep them aired up. If I were to buy a camper myself I would figure out how swap for some E rated truck tires instead of cheap trailer specific tires.
